Mechanical Circulation & Aeration
Using a
Force 7 Aerator

Perfect for small to medium water bodies. This is a non-ornamental solution that injects and circulates oxygen into your water body to control any algae or aquatic weeds and maintain a healthy looking clear water. Great for lakes and ponds in farms, golf courses, nurseries and wineries in which functionality is more needed than the visual appearance.

Lakes and treatment ponds water bodies are typically high in nutrients and become stagnant over time due to a lack of aeration and circulation, which results in an overgrowth of pond algae and weeds. The consequent accumulation of detritus and bottom sludge compounds the problem, and thus, the cycle of stagnation continues.

Short Term Solution Chemical Application

Depending on the status of the algae in the water body the use of algaecides may be required at the start of the project to get rid of all accumulated algae or aquatic weeds before the application of mechanical circulation and aeration for long term results. We use a range of algaecides depending on the type of algae in your water body. For more information on the types of algae click here.  Most commonly we use Cupricide, Kupramine or water clear. When submitting your enquiry, please include an image of your water body with algae so we can recommend the best algaecide

Long Term Solution Mechanical Circulation & Aeration

We use a combination of mechanical circulation and aeration to return and maintain the water body in a healthy state. Aeration targets the cause of the problem and yields the best results, whilst remaining environmentally friendly. Essentially, lakes and ponds become stagnant due to a lack of oxygen in the water. The result of stagnation is a bottom sludge of detritus that cannot be broken down. Mechanical aeration reintroduces oxygen into the water column by moving the water, which encourages bacteria (in the oxygen) to naturally degrade the accumulation of detritus. The water clears and begins to return to its natural state.

Sustainable Long Term Solution Microbial Inoculation

Adding living bacteria that can produce the type of enzymes we need for the degradation of a certain type of algae or aquatic weed. Even if some of these enzymes are degraded, the bacteria will continue to produce them as long as the food (Algae) is available.


Applying mechanical aeration and circulation depends on a number of things including the type of application, the size and depth of your waterbody, the age of the water body and the type of algae or aquatic weeds it has. The use of Force 7 aerator is perfect for small to medium water bodies with a total volume of less than 5 Megaliters. Remember this is a non-ornmental water feature, which means the whole action happens under the water without any visual display.

Force 7 Aerator & Circulator

Force 7 Aerator & Circulator

A submersible lake and pond aerator, which oxygenates by drawing in and dispersing air at depth, in the form of micronised bubbles.

The Force 7 is a compact, robust, but lightweight, easily handled aeration device with unrivalled performance characteristics. Being submersible in design, the unit can be positioned at depths of up to 15.0 metres below the water surface via the use of extension snorkels. The Force 7 lake and pond aerator can also be configured to mitigate stratification of water bodies by creating influencing currents at the surface or at depth, by pivoting the motor axis up to 35º above and below horizontal for specific applications.

Component Construction:

Central Motor Housing: Marine Brass
Propeller: Reinforced Plastic

Clear & Healthy Looking Water Body Free from any algae or aquatic weed

Depending on the age of your water body and the type of algae or aquatic weeds in it you should expect great results within the first few weeks from applying the algaecides. After, when installing your mechanical circulation and aeration system, your lake and pond should maintain in great shape.

Coral Coast Barramundi

Coral Coast Barramundi is located in the beautiful Whitsunday region of QLD and produces high-quality saltwater barramundi. Our farm consists of 24 x 1.2Meg plastic-lined raceways and is a fully integrated system, comprising of broodstock, hatchery, nursery, grow out and packing shed.  Coral coast Barramundi and BioRemedy have worked closely together over the past 10+ years and the  products and services they provide are second to none. Our farm has worked in conjunction with  BioRemedy on a number of aeration, circulation and oxygen injection projects.  In particular, we rely heavily upon the Acqua & Co Force 7.2 as it delivers oxygen injection and mixing like  no other product on the market. The Force 7.2 aerators have allowed us to at least double our production  and achieve excellent Feed Conversion Ratios coupled with the use of oxygen.  Corey Sander, Growout Manager, Coral Coast Barramundi

Maintenance Schedule

The Acqua & Co. FORCE 7 Submersible Aspiration Aerator is a high efficiency machine designed to allow continuous operation in outdoor ponds and lakes. Due to its short motor shaft design and effective sealing arrangement, the FORCE 7 has a low maintenance requirement.

However, it is important to provide effective preventative maintenance to ensure a long life from the aerator. It is recommended that an inspection of the primary seal is performed yearly, with inspection of the secondary seal and bearings performed every two years. It is recommended that the maintenance schedule provided be followed to ensure effective management of your asset
